The guide rails, which are the inner faces of the vertical guide rails '8, The guide rails are provided at their lower. ends with inwardly curved resilient per tions' 13 set at aslight inclination and adapt;

Theguide rails, by the-particular construetion-of their upper. and lower portions, auton'i'atically guidefthe wiper in the upward and downward, movements thereof. By arranging the-wiper out of engagement with 'j'the glass during'its upward movement, the

' wiper'is 'relieved of friction and requires etifbut little'efiort'to return it to its elevated e izarmuial projecting portions of the vot-fdcarry upper and lower arms 14 and -115 'arrang'ed'in pairs and disposed at an inwithin the openings 16 and 17'offithe arms 14 and 15, and having thesaid antifriction' in anyother desired manner, and the lower varm 15 is of greater length than the upperf;1.- arm 14. The openings 16 and 17 of the arms 1 14 and 15 receive antifriction rollers 18 and 19 of upper and lower links 20 and 21,

which connect the arms with upper and lower'metall'ic tapes or strips 22 and 23. The links 20 and 521, which are rectangular, are'composed of spaced sides and transverse connecting portions; the outer transverse connecting portions being secured to the adjacent ends of the tapes and the inner transverse connecting portions being arranged rollers 18 and 19 mounted on them; The

:rollers enable the links to move frictionlessly in theope'nlngs 16 and 17 of the upper and lowerj arms 14: and 15 during the pivotal movement otthe wiper, which is"tiltable on its pivot'to carry itrtc and fromthe 'positions illustrated-in Figs. at and-10 of the brscl'tet f fii' mamtlmod clination. These arms, which consist of f :Jloops, maybe formed ot a continuous strip of'me'tah'as clearly illustrated in Figs. 7 and;

I 8 of the drawings, but they may be made upwardly from the lower drawings. When the wiper is in the position illustrated in Fig. 4 of the drawlngs, the arms extend downwardly from the pivot 6, and the upper roller is arranged at the inner end of the upper arm 14, while the lower roller is located at the outer end of the lower arm 15, as clearly-illustrated in "having moved,inwardly from the outer end thereoflthrou gh the; tilting of the wiper.
